Express Sport brings you the best pictures from Arsenal's latest training session ahead of their Europa League clash with Cologne on Thursday (6pm)

Ozil and Sanchez were both snapped putting in the hard yards defensively as Arsenal trained ahead of their Europa League clash with Cologne tomorrow (6pm).

The duo are not known for their tackling abilities, with Ozil in particular often criticised for his poor work rate off the ball.

However, both Arsenal stars seemed in the mood at London Colney this afternoon, putting in sliding tackles on less-experienced members of the Gunners squad.

Arsene Wenger looks set to rotate his players for tomorrow’s match with qualification to the knockout stages already secured, so Ozil and Sanchez may not be called upon to show off their defensive skills just yet.
